Plaintiff William Tuttle leased restricted Indian land in Riverside County, California, for a term of 50 years. The land is owned by the United States in trust for the Colorado River Indian Tribes. In 2010, the Bureau of Indian Affairs terminated the lease, finding that Mr. Tuttle had violated several of its provisions. The termination decision was affirmed by the Interior Board of Indian Appeals. The Bureau of Indian Affairs and the Interior Board of Indian Appeals are constituent agencies of the Department of Interior. Plaintiff sued the Secretary of the Interior, in her official capacity, complaining that the agency’s decision to terminate was arbitrary and capricious, in violation of both the Indian Long-Term Leasing Act and the terms of the Lease itself. Having reviewed the entire administrative record, the Court concludes that the agency acted reasonably on the record before it and within its authority. The Secretary’s motion for summary judgment will be granted.
